Salicylic acid and jasmonic acid crosstalk in plant immunity
Essays in Biochemistry, 2022Abstract The phytohormones salicylic acid (SA) and jasmonic acid (JA) are major players in plant immunity. Numerous studies have provided evidence that SA- and JA-mediated signaling interact with each other (SA-JA crosstalk) to orchestrate plant immune responses against pathogens.

Jasmonic Acid Catabolism in Arabidopsis Defence Against Mites
Plant Science, 2023Jasmonates are essential modulators of plant defences but the role of JA-derivatives has been scarcely studied, particularly in the plant-pest interplay. To deepen into the JA catabolism and its impact on plant responses to spider mite infestation, we selected the Arabidopsis JAO2 gene as a key element involved in the first step of the JA-catabolic ...

Abstract Methyl jasmonate (MeJA) is a volatile jasmonate compound commonly used to induce defense responses in spermatophytes. This study reports that airborne MeJA‐d 3 , deuterated MeJA, increases the levels of (dinor‐)12‐oxo‐phytodienoic acids [(dn‐)OPDAs] and jasmonic ...

Jasmonic Acid–Amino Acid Conjugation Enzyme Assays
2013Jasmonic acid (JA) is activated for signaling by its conjugation to isoleucine (Ile) through an amide linkage. The Arabidopsis thaliana JASMONIC ACID RESISTANT1 (JAR1) enzyme carries out this Mg-ATP-dependent reaction in two steps, adenylation of the free carboxyl of JA, followed by condensation of the activated group to Ile.

A radioimmunoassay for jasmonic acid
Biochemie und Physiologie der Pflanzen, 1984Summary A radioimmunoassay (RIA) for the natural plant growth regulator jasmonic acid (JA) was developed. The antiserum was raised in rabbits against (±)-JA linked to bovine serum albumin. As tracer tritium labelled (±)-JA (spec. act. 7.4 ×109 Bq×mmol−1) was used.

(—)-Jasmonic acid [(—)-JA (Ia)] and its methyl ester (Ib) were found to be widespread in plants [15] and are considered to represent a new type of native PGRs with hormone-like properties [22, 23]. Further members of the group are (H-)-7-iso-JA (II), known as the major product of JA biosynthesis in fruits of Vicia faba [16] and in the fungus ...
